Quality Control

Our Sodium Hydroxide Monohydrate is produced under stringent quality management systems. We offer various grades, including Industrial, Technical, and high-purity Reagent grades, with specifications tailored to meet diverse application needs. Product quality is verified through rigorous analytical testing, including assay, impurity profiling, and physical characterization. Certificates of Analysis (COA) are provided with each shipment to ensure traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and organic solvents. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F).
